研究了13种类人猿灵长类动物长骨关节表面积的生物力学尺度。有人提出，关节表面积应与体型呈正异速增长，以保持小型和大型动物关节相对恒定的安全系数，并且在表现出从根本上改变肢体负荷的特殊运动行为的物种的肢体关节中，可能会出现总体缩放模式的改变。在类人猿中，腕部灵长类动物，白掌长臂猿（hyloates lar）和黑手蜘蛛猴（Ateles geoffroyi）被用来验证这一假设。在12个肢体关节中，有11个关节的总关节表面积呈显著的正异速增长。观察到的种间异速生长模式支持了负重是关节设计的主要制约因素的假设。这种正的种间异速也反映在种内水平上，较大物种的较大关节显示出显着的种内缩放。悬吊物种与类人猿的整体模式没有明显的差异，尽管它们的肢体关节压缩负荷减少，即使在控制关节活动后也是如此。这些结果表明，虽然运动行为的进化变化导致关节负荷的显著增加，可能伴随着对关节表面积增加的选择，但采用减少肢体负荷的运动动作可能对关节形态没有选择性影响，在这些情况下，关节设计将反映祖先运动条件的生物力学。
Biomechanical scaling of long bone joint surface areas was investigated in 13 species of anthropoid primates. It was proposed that joint surface areas should scale with positive allometry with respect to body size in order to maintain relatively constant safety factors for joints in small and large animals and that modifications from the overall pattern of scaling may be expected in the limb joints of species exhibiting specialized locomotor behaviours that radically alter limb loading. Within anthropoids, the brachiating primates, white-handed gibbons (Hylobates lar) and black-handed spider monkeys (Ateles geoffroyi), were used to test this hypothesis. Total joint surface areas were found to scale with significant positive allometry in 11 of 12 limb joints. The observed pattern of interspecific allometry supports the hypothesis that weight bearing is a major constraint on the design of joints. This positive interspecific allometry is reflected at the intraspecific level as well, with larger joints of larger species showing significant intraspecific scaling. Suspensory species showed no significant deviations from the overall anthropoid pattern, despite their reduced compressive loading of the limb joints, even after controlling for joint mobility. These results suggest that, while evolutionary changes in locomotor behaviour that produce significant increases in loading of a joint may be accompanied by selection for increased joint surface areas, adoption of locomotor repertoires that reduce limb loading may have no selective effect on joint morphology, and joint design in these cases will reflect the biomechanics of the ancestral locomotor condition.
